Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed July 26, 1915. Serial No. 42,008.

To all whom it may concern Be it known that'I, HARRY EBERT, a citizen ofthe United States, residing at Frederick, in the county of Frederick andState of Maryland, have invented new and useful Improvements inShutter-Bowers, of which the following is a specification.

The present invention relates to shutter bowers and fastenings of thattype in which a pivoted rod combined with a bowing plate and fasteningbracket is utilized to lock the blinds in closed position and to holdthem in the different positions to which they may be bowed or entirelyopen.

The present invention has to do only with the bowing rod and itssupport, and the other instrumentallties which make up the device may beof the usualor any suitable type.

The invention has for its object to provide a bowing rod which may becheaply constructed and assembled and which will serve both as a rightor left rod without the necessity of specially constructing the rod andits supporting bracket for right and left hand use. 7

In order that the construction may be clear to those skilled in the art,I have shown one embodiment of my invention in the accompanyingdrawings, in which- Figure 1 is a perspective view of so much of awindow-frame and blind as will illustrate the application of myinvention.

Fig. 2 is a front elevation of the bowing rod and its supportingbracket. V

Fig. 3 is a rear elevation of the rod sup porting bracket.

Fig. 4 is a horizontal sectional view of the bracket.

Fig. 5 is a rear elevation of the bracket with the rod-supporting postremoved.

Fig. 6 is a vertical sectional view of the bracket.

Referring to the drawings by numbers like numbers indicating like partsin the several views. 10 indicates the rod bracket or supporting platewhich may be of any desired form, and is provided with the usual screwholes to permit its attachment to'the blind.

The said plate 10 is provided with an opening 11 throu h which the rodcarrying post 12' is passe and in which said post wivels, the said post12 having a base 13 which seats in a suitable socket in the bracket 10.The said socket is provided with a lug 1a which is adapted to engage oneof a plurality of recesses 15 formed on the base 13' of the post, theserecesses as shown being preferably twoin number and diametricallyopposed so that by simply swiveling the post either of the recesses 15may be brought into engagement with the lug l4 and a right or left handbowing rod will result.

'Theend of the post 12 has a hole therethrough to receive the offset orturnecbover end 16 of the bowing rod 17, the free end of the rod: beingoffset or turned-over so as to provide means for engaging the sockets inthe usual bowing plate with which the device is used. It will beobserved that the bowing rod has its ends turned-over or offsetsymmetrically so that in assembling the workman may insert either endinto the hole 18in the post and rivet or head down the end of the rod soas to secure it to the post, and this from a practical standpoint is ofconsiderable value as the necessity for the workman selecting aspecially prepared end for the purpose of assembling the post and bowingrod is done away with.

1 The aperture 11 inplate 10 is of such size that the rod 17 and post 12maybe assembled and readily passed through the opening 11 so that thework of assembling the post and bowing rod is very much simplified.

The recesses and lug, while they permit a limited swiveling movement ofthe post and bowing rod so as to provide for the necessary rise and fallof the rod to disengage and engage it with the socket plates on thewindow-sill, will, at the same time maintain the rod in the same generalhorizontal position which. it must be maintained in. V

The socket 11 and the base 13 fit loosely so as to permit free swivelingof the post,

' but at the same time are sufiiciently tight to preventany tilting orrocking laterally, and the post 12 fits turning fit in thehole 11.

In order that there may be no danger of the base 13 binding when thebracket 10 is screwed to the blind or other support, I preferablyprovide the bracket with a slight rib 19 which is slightly above theplane of the base 13 so that the post and base will swivel freely andyet the base will be preof the post vented from tilting or rocking, andits move-' ments confined to the swiveling or rotating movement aroundthe axis of the post.

It will be obvious that slight changes in design andmeohanicaldetailsmay be made with an easy 1. In a device of the classdescribed, a

supporting-plate having a post-receiving aperture and a recessencircllng said aper-V true, a

reversible rod-supporting post mounted to swivel in said aperture andhaving a base engaging said recess, interengaging means on said plateand post to limit the swiveling movement of said post in either of itspositions, and a bowing rod pivotally mounted on said post.

V 2. In a device of the class described, asupporting-plate having apost-receiving aperture and a, recess encircling said aperture, areversible rod-supporting post having a notched base mounted to swivelin said aperture with said base seated in said recess, a lug on saidplate to engage a recess in the base of said post to limit the swivelingmovement of said post, and a bowing rod pivotally mounted on said post.In a device oi. the class described, a su morting-plate having aiost-receiving aperture and a recess encircling said aperture, areversible rod-supporting post mounted to swivel in said aperture andhaving a base seating in said recess, opposed notches on base of saidpost, a lug on said plate to engage one or the other 01": said notchesand 1111111: the swivellng movement of 'said post, and a bowing rodpivotally mounted on said post.

t. In a device of the class described, a supporting-plate having apost-receiving aperture, a rod-supporting post having a flanged basemounted to swivel in said aperture, an offset rib on said plate to giveswiveling clearance to said flanged base, and a bowing rod pivotallymounted on said post. 7 In a device of the class described, a supportingplate having a post-receiving aperture therein, and a reversible rod supporting post having a flange thereon, said post adapted to be insertedin the aperture :troni the underside of the supporting plate and heldagainst removal by said flange.

In a device of the class described, a supporting plate having apost-receiving ure and an unbroken recess encircling said aperture, areversible rod-supporting post having a base seating in said recess,said post adapted to be inserted in paid aperture from the underside ofthe sup porting plate and swivel in said a erture, opposed notches onthe base of said post, and a lug on the plate adapted to enga one of thenotches on the base to limit the swiv .eling action 01'? said post.
